It's right there on your qutebrowser link, dwb is first on the "Similar Projects" list (Scroll down) their "Unmaintained" comment leads to the reddit thread you mention, mind you that thread is 1 year old and the user/post is deleted: https://www.reddit.com/r/linux/comments/2huqbc/dwb_abandoned...

Ah, I see. Either way, I was eager to switch at the time as webkitgtk had a bad bug in it that would cause dwb to insta-crash on loading a page about once an hour and which wasn't getting fixed. Qutebrowser is based on Qtwebkit and didn't have the same issue, so I jumped ship pretty early in its development.
